EBD are seeking graduates in areas such as animal behaviour, zoology, plant biology, biology,
ecology or related fields to carry out a 3 month internship at their office in Seville.
The projects they require interns for are listed below:
1) THE EFFECTS OF FIRE ON ANTS AND OTHER ARTHROPODS: A STUDY ON
DIFFERENT DEPTHS
Project description:
This project will involve assisting in the investigations to support a Doctoral thesis on “The effects
of fire on ants and other arthropods: A study on different depths” at the Department of Ethology and
Biodiversity Conservation of the EBD-CSIC.
The project will involve analysing the consequences of fire on four groups of epigeal and aerial
arthropods (ants, beetles, spiders and bees) often used as bioindicators for ecosystem recovery. The
aim of the thesis is to understand how species, communities, and ecosystems respond to
environmental changes caused by fire. This will be done by studying the its effects on: 1) Patterns
of abundance, richness and biodiversity of ants, beetles, spiders and bees, 2) functional diversity of
ants, beetles, spiders and bees, 3) populations genetics in the communities of ants, 4) the dominant
relationships in the communities of ants, 5) the use of trophic resources by ants and 6) the
temperature resistance in ants.
Tasks to be carried out by the intern:
- Literature review
- Research features of the history of life in the literature
- Computerize data
- Separation and classification of the extracted material in the field
- Determination of ants, beetles , spiders and bees
* basic knowledge in entomology are needed.

2) EXPERIMENTAL EVOLUTION OF SEXUAL CONFLICT
Project description:
The trainee will participate in a project that centres on a comprehensive empirical evaluation of the
evolution of sexual conflict traits in a beetle model system. Sexual selection and sexual conflict
(when the evolutionary interests of males and females differ) are potent evolutionary forces that
underlie the expression of numerous traits in males and females and that fuel complex
coevolutionary interactions between the sexes. The project rests on a large experimental evolution
approach consisting of several lines of beetles that have been maintained for over 30 generations
under different selection treatments (presence/absence of sexual selection and presence/absence of
population subdivision). The project brings together several areas in the study of evolutionary
ecology and utilizes powerful methods to address questions at the cutting edge of sexual selection
theory. The trainee will assist members of the research group in a series of experiments and assays
on the individuals from the selection lines. These experiments will address several topical questions
in relation to the dynamics of sexual conflict in response to the experimental manipulation of
selective forces (in particular mating system selection history, population spatial structure selection
history, and their interaction).
Tasks to be carried out by the intern:
Specifically, the trainee will carry out (or assist in carrying out) some of the following tasks:
- Setting out mating assays among the individuals from the selection lines.
- Helping out with running of assays to examine variation in traits responding to the different
treatments of selection.
- Helping out with the collection of the material and samples for assaying the reproductive success
of individuals.
- Preparation of samples for the measurement of male and female behavioural and reproductive
traits that play a role in (or are the consequence of) sexual conflict.
- Measurement of productivity rates in the different selection lines.

3) ECOTYPIC DIVERGENCE IN LONG-LIVED
MEDITERRANEAN AND TROPICAL AREAS
TREES
ORIGINATING
FROM
Project description:
Species distributed across a wide range of environmental conditions are subjected to
differential selective pressures. Long-term selection can lead to the development of
morphological and physiological adaptations to the local environment, generating ecotypic
differentiation in important functional traits. In this project, we aim to study the role of natural
selection on ecotypic divergence in two widely distributed oak tree species: Quercus faginea
(Western Mediterranean) and Quercus oleoides (Neotropics) plus a narrowly distributed tree:
Prunus lusitanica. We are particularly interested in testing how adaptation to different soils
and climatic regimes has driven intraspecific genetic differentiation in ecologically-important
traits of these species.
Tasks to be carried out by the intern:
- To analyse leaf morphological traits in herbarium specimens collected in natural conditions as
well as seedlings growing in common garden experiments.
- To investigate leaf (e.g. stomatal traits) and stem anatomy (e.g. xylem traits) using
microscope images.
- To participate in the development of a new experiment that will be established under
controlled conditions. The student will be encouraged to contribute in the experimental
design, formulation of hypotheses and implementation of the study.
- To measure population genetic differences and intrapopulation genetic diversity
using/learning quantitative genetic approaches that will allow students to gain experience in
data analyses.

4) INTRODUCTION TO PLANT EVOLUTIONARY ECOLOGY AND EPIGENETICS
Project Description:
There has been a recent upsurge of interest on the ecological and evolutionary significance of
epigenetic processes, which involve heritable phenotypic changes unrelated to alterations in DNA
sequence. In the case of plants, mounting interest on epigenetic processes has been largely
promoted by results showing that in some model species epigenetic changes in the phenotype can
be induced by the environment and are often passed without alterations across generations. DNA
cytosine methylation is a well-established epigenetic mechanism and the most studied one in plants.
We will focus on DNA methylation and explore the general hypothesis that intense and recurrent
water stress will induce heritable changes in DNA methylation that will differ between two nonmodel species, one characteristic of Mediterranean poor soils and, thus, usually facing this stress
(Erodium cazorlanum) and the other characteristic of deeper soils and with a broader distribution
range (Erodium cicutarium).
Tasks to be carried out by the intern:
The student will assist on greenhouse experiments aiming to test this hypothesis. The student will
learn concepts of experimental design, methods of plant evolutionary ecology (phenotyping and
fitness estimates) and will be introduced to molecular (epi)genetics. Among student’s tasks we
include: preparation of seeds (counting, weighing, sowing, watering …), germination and survival
monitoring, seedling phenotyping (number of leaves, leaf length, leaf specific mass, …), adult
phenotyping (date of flowering, number of inflorescences, number of flowers/inflorescence, flower
size, …). Student’s training will also benefit from attendance to the weekly seminars held at EBD.

5) FROM CLIMATE TO PLANTS, INSECTS, AND BATS: THE STAPLE ISOTOPE
CONNECTION IN ECOSYSTEMS
Project Description:
Ecological research is often concerned with trophic interactions (“who eats whom”) and how these
interactions change through time. Stable isotope analysis is a fundamental method in ecology
because it allows tracking the food sources and the movements of an animal. However, recent
research by the host scientist (Popa-Lisseanu et al. 2015, PLoS ONE 10(2): e0117052) has shown
that isotopic variation in animals can also reflect climatic changes, thus complicating the evaluation
of trophic relationships and movement patterns.
There are several mechanisms through which climatic variation could drive isotopic variation in
animals. First, physiological condition could affect the way that isotopes from food are incorporated
into the animal’s tissues, and physiological condition often tends to follow climatic cycles. A more
straightforward explanation, however, is that climatic variation, particularly water stress, affects the
way that plants regulate nutrient uptake and subsequently influences plants’ isotopic values. As a
consequence, plants’ isotopic values change seasonally, and these temporal changes are passed on
from plants to herbivores, from herbivores to carnivores, and so on, therefore being mirrored by all
members of the ecosystems, with a certain time lag between them.
By investigating simultaneously climatic variables and isotopic values at different trophic levels,
the project within which this internship is offered tests the hypothesis that climatic variation creates
ecosystem isotopic baselines that propagate up the food chain. The results of the project are
expected to improve the field of stable isotope ecology by showing how to correct isotopic data for
environmental variation, and will therefore allow much more accurate estimates on dietary inputs
and movement patterns of organisms. The study is being conducted in the Doñana National Park.
This protected area located in southwest Spain is one of Europe’s largest and most important
wetland reserves and comprises many different biotopes at the interface between aquatic and
terrestrial ecosystems. The model food chain selected for this research is the one composed by
plants, insects and the soprano pipistrelle bat, Pipistrellus pygmaeus. Plant material, insects and
skin tissue samples of bats are collected at weekly or biweekly intervals to investigate temporal
variation within and across trophic levels.
The intern will have the opportunity to participate in research at Spain’s leading institution in
terrestrial ecological research, to learn basic procedures and instrumentation common to many
different laboratories and to gain insight into stable isotope analysis, a method widely applied in
many fields of basic and applied research, not only in ecology, but also food health, anthropology,
migration research, climate research, forensics and criminalistics, among others. He/she will also
have the opportunity to participate in field work in the charismatic Doñana National Park.
Tasks to be carried out by the intern:
- Perform sample preparation for stable isotope analysis of plant, insect, and bat skin samples at the
stable isotope laboratory (LIE) of the Doñana Biological Station in Seville: washing, drying,
grinding and fine weighing of samples to target weight, mounting samples in tin/silver capsules and
organizing them into trays
- Occasionally assist in fiel work in the Doñana National Park
- Enter data into the computer
Requirements
The candidate must feel comfortable working in the laboratory. Good hand and eye coordination,
attention to detail, and patience are essential since the samples handled are minute and the lab
procedures are laborious. Flexibility in working schedule is necessary to accommodate to lab
equipment availability times.

6) USE OF STABLE ISOTOPE ANALYSIS TO REVEAL WINTERING STRATEGIES OF
MIGRATING EURASIAN HOOPOES
One-fifth of the world’s bird species are migratory. Delineating migratory connectivity and
understanding the consequences of wintering site choice for individual fitness is particularly
important in the face of the steady decline observed in populations of long-distance Palaearctic–
Afrotropical migrants. However, wintering ecology of migratory birds is much less understood than
breeding ecology. The ‘serial residency hypothesis’ tries to explain how long-distance migratory
birds select wintering sites. The term ‘serial residency’ refers to the prediction that a migrant bird is
likely to rely on a series of individually unique, temporally and spatially connected sites. We will
use stable isotope analysis to test this hypothesis in the European hoopoe (Upupa epops epops), a
trans-Saharan migrant that winters primarily in the Sahelian and savanna belt south of the Sahara.
Hoopoes typically prefer open foraging habitats with bare ground, short grassland and sparse
vegetation. Following the predictions of the serial residency hypothesis, we expect that juveniles,
lacking previous migratory experience, will end up in a more diverse range of habitats, including
less suitable habitats, than adults. We also expect that adults, and young that have found suitable
habitats, will show fidelity to their wintering sites. To test this, we will compare stable isotope
values of feathers of adult and young hoopoes that have been captured during the breeding season in
Switzerland but have grown their feathers in their wintering grounds in Africa. Stable isotopes are
geographical and food markers that can give us information on location of feather growth, as well
as type of habitat and food sources consumed.
The intern will have the opportunity to participate in research at Spain’s leading institution in
terrestrial ecological research, to learn basic procedures and instrumentation common to many
different laboratories and to gain insight into stable isotope analysis, a method widely applied in
many fields of basic and applied research, not only in ecology, but also food health, anthropology,
migration research, climate research, forensics and criminalistics, among others. Our team also
works on other research projects that involve field work in the Doñana National Park, so, if the
intern desires it, he/she will also have the chance to visit the Doñana Biological Reserve and
occasionally assist in field work.

7) PROJECT: FORAGING ECOLOGY OF LEAR’S MACAWS
CONSERVATION IMPLICATIONS: A STABLE ISOTOPES APPROACH
AND
ITS
Project Description:
The Lear's Macaw, Anodorhynchus leari, is one of most range-restricted and threatened parrot
species of the world, being endemic to Brazil. Despite a recent population increase in the last 10
years, the entire population is around 1300 individuals of which 80% were non-breeders. Attending
to the conservation problems compiled by IUCN, the protection of nesting sites reduced nest
poaching to the point that it is not currently considered as a major threat. Current threats seem to be
rather related to food availability and the foraging behavior of the species. Lear’s macaws are
thought to forage mostly on licuri palm nuts (Syagrus coronata) and licuri palm-stands have been
vastly reduced by livestock-grazing and agriculture expansion. On the other hand, Lear’s macaws
forage on maize crops when palm nuts are supposedly scarce. This causes persecution and hunting
by farmers, to the point that a main conservation action consists on compensating farmers for crop
losses. Despite these conservation problems, there is no accurate information on the diet and food
requirements of the species. Our research team has compiled a variety of plant species consumed by
Lear’s macaws in the Caatinga dry forest, and given the difficulties to gather unbiased foraging
observations of Lear’s macaws, our project aims to assess the diet of the species using the most
advanced techniques to determine animal diets through stable isotope analyses. The project benefits
from the previous monitoring of the population and an unprecedented large number of Lear’s
Macaw biological samples collected during seven years (2008-2015). The isotope signatures of C
and N in blood and feathers tissues of the macaws and their putative food resources, combined with
the individual identification through genetic analyses, will allow us to assess the diet of the species,
its sources of variation (between individuals, ages, local populations, and years), and its
relationships with inter-annual variations in rainfall and breeding success. The results of this project
will undoubtedly contribute to clarify the actual role of licuri palm nuts, other wild plants, and
maize crops on the diet and population dynamics of the species.
Tasks to be carried out by the intern

13) LIGHT POLLUTION AT PROTECTED AREAS: IS NATURA 2000 PROTECTING
NATURAL NIGHT SKIES?
Light pollution (altered levels natural light in the night landscape) is annually increasing globally at
6%. Many of protected areas are currently affected (or they will be affected in the future) by this
type of pollution which has negative effects on organisms and ecosystems. This project aims to
assess the light pollution trends in the Protected Areas of the largest network of protected areas in
Europe, Nature 2000, by using satellite imagery of the last 20 years.
Requirements: Although Doñana Biological Station has a laboratory on GIS and remote sensing
(LAST-EBD), the student should be familiar with GISs (ArcGIS, Qgis or R) and scientific papers.
Offer: It is expected that the project can be published in a conservation or environmentalist journal
as Environmental Conservation, Environmental Pollution, Conservation Biology, or Journal of
Environmental Management). We offer co-authorship to the student or leadership (first author)
depending on his/her analytic and writing skills.

15) ESCAPE FROM NATURAL ENEMIES IN INVASIVE POPULATIONS OF IBERIAN
WALL LIZARD
Project description:
The work will be developed in the framework of Research Project NATALIEN, which evaluates
three different processes mediating the resistance of natural communities against biological
invasions, using two focal species: a global invader, the Argentine Ant, and a local invader, the
Ibiza Wall Lizard. The work will focus on testing one of these processes, the escape from natural
enemies, using samples from the native and invasive populations of the Ibiza Wall Lizard. This
hypothesis predicts that invasive lizard populations should have a decreased load of parasites and
pathogens, following their stochastic loss during the early colonization stages in which few
colonists are present.
Tasks to be carried out by intern:
The student will undertake DNA-based determinations of enterobacteria (Salmonella spp.) in faecal
samples from Ibiza wall lizard. The method involves the extraction and sequencing of bacterial
DNA, as well as data analysis and reporting, and will be developed in the Laboratory of Animal
Ecophysiology under the supervision of Dr. Elena Gomez Díaz and Dr. Luis Santamaría

KEY
ECOSYSTEM
SERVICES
MEDITERRANEAN FORESTS THREATENED BY CLIMATE CHANGE
IN
Project description:
The work will be developed in the framework of Life+ Project ADAPTAMED, which aims at
increasing the resilience of Mediterranean forest ecosystems against climate change, thus preserving
the key ecosystem services they provide. The project develops an adaptive management programs
that includes the design, implement and monitoring a number of management interventions in three
iconic Natural Protected Areas of Spain’s Mediterranean region, chosen to represent three major
ecosystem types: the coastal pine forests and wetlands of Doñana National Park, (2) the mountain
oak, pine and juniper forests of Sierra Nevada National Park, and (3) the semiarid shrubland of
Cabo de Gata Natural Par. Key ecosystem services targeted by the interventions and subsequently
include, among others, carbon storage, soil fertility, pollination, pasture production, pest control,
water provision, prevention of forest fires – and, more generally, the conservation of biodiversity.
Tasks to be carried out by intern:
The student will participate in the different activities of the monitoring program at the Doñana
National Park, including the design and implementation of field work (data collection); the
preparation, revision and analysis of the resulting datasets (data analysis). Monitored variables
include tree growth, shrubland cover, grassland productivity, and the abundance and composition of
songbirds, pollinators, ungulates, rodents and reptiles. Emphasis on a subset of these variables will
be arranged depending on interest and planning/logistic limitations. Interested candidates could also
participate in ongoing work using remote sensing, phenocams and/or camera traps.
